Subject: bus id in PHY Abstraction Layer

Hi,

I made a quick shot to port the at91 network driver to the phy
abstraction layer. While doing so I stumbled upon the
(struct mii_bus)->id field. Currently the network driver registering the
bus has to set this field. au1000_eth.c for example uses 0 or 1. mii-fec.c
uses the id field of the corresponding platform device, which will start
from 0, too. So if a second ethernet driver comes around the id fields
will clash. I think the PAL has to assign the id field instead of the
network driver. Maybe a id convention like "mii_fec.x:yy" where x is a
running number and yy is the phy address would do it. Any opinions about
that?

Sascha
